Megan Waterman's remains were found near three other sets of remains belonging to sex workers who advertised their services on Craigslist. Police believe a serial killer may be responsible for their deaths.

A New York man has pleaded guilty to federal charges that he transported one of the victims of a suspected Long Island serial killer across state lines for prostitution.

Akeem Cruz was with Megan Waterman of Maine the night she disappeared from a Long Island hotel in June 2010. He has been identified in some reports as her boyfriend. Waterman's body was later found dumped along a remote beach parkway. Police have since found nine other bodies along the highway.

Cruz admitted Wednesday in federal court in Brooklyn that he transported women from Maine to New York so they could meet clients for sex.
